这个写个windows服务比较好：
C# code

    public partial class MyServer : ServiceBase
    {
        public MyServer()
        {
            InitializeComponent();
            this.ServiceName = "MyServer";
        }
        Thread th = null;
        bool isStop = false;
        protected override void OnStart(string[] args)
        {
            if (th == null)
            {
                th = new Thread(new ThreadStart(delegate
                {
                    while (!isStop)
                    {
                        //上午10点和下午4点
                        if ((DateTime.Now.Hour == 10 || DateTime.Now.Hour == 16) && DateTime.Now.Minute == 0)
                        {
                           //执行你的任务
                        }
                        Thread.Sleep(60000);
                    }

                }));
            }
            th.Start();
        }

        protected override void OnStop()
        {

            isStop = true;
            Thread.Sleep(3000);
            if (th != null)
            {
                th.Abort();
                th = null;
            }
        }
        protected override void OnPause()
        {
        }
        protected override void OnContinue()
        {
        }
        
    }

Timer定时器，右下角托盘，再放入系统启动项。我当年有个程序就是这么做的，实际情况很不错。
